Specification of Letters Patent.

Patented May 30, 1916.

Application filed January 27, 1914. Serial No. 814,729.

To all whom it may concern."

Be it known that I, JAMns ALLEN HUG- GINS, a citizen of the United States, residing at Florence, in the county of Florence and State of South Carolina, have invented certain new and useful Improvements in Subsoil-Plows, of which the following is a specification.

' This invention relates to a. subsoil plow, and the principal object of the invention is to provide an improved means for constructing a subsoiler whichwill permit of vertical adjustment of the point-carrying standard; to provide improved means for pivotally mounting the subsoiler beam; and to also provide improved means for limiting the pivotal movement of the beam in one direction.

Another object of the invention-is to so connect the standard and subsoiler beam that the standard may be easily adjusted and securely held in the adjusted position.

Another object of the invention is to provide means for permitting transverse movement of the standard after being adjusted.

Another object of the invention is to so construct the front-end portion of the subsoiler beam that when desired, the subsoiler may be easily removed from the plow.

Another object of the invention is to so construct the brace which is carried by the main plow beam and engages the subsoiler beam that the brace may be longitudinally adjusted, and to so construct the free-end portion of the brace that it will engage the subsoiler beam at right angles and prevent the sub-soiler from rising when striking hard places in the soil.

This invention is illustrated in the accompanying drawings wherein- Figure 1 is a side elevation of the subsoil plow with the point of the main plow partly broken away; Fig. 2 is a longitudinal sectional view taken algng the line 22 of Fig. 1; Fig. 3 is a sectional view taken along the line 33 of Fig. 1; Fig. 4 is a view taken along the line H of Fig. 1 and showing the bracing bar in top plan; Fig. 5 is a perspective view of the standard and rear-end portion of the beam for thesubsoiler.

The main plow structure comprises the plow beam 10, digging point 11, handle 12, and handle braces 13. The point 11 is se cured to the beam 10 by means of the bolts 14; and 15 which extend through the plow beam 10 to' engage a U-shaped housing 16.

The bolt 14 only passes through the inner wall of the housing 16, but the bolt 15 extends entirely through the housing and forms a pivot pin for the beam of the subsoller.

The subsoiler is provided with a standard 17 which carries the digging point 18 and fits against the front face of the verticallyextending rear arm 19 of the beam indicated in general by the numeral 20. This beam 20 is carried across the upper end of the standard 17 to form a bridge 21 from which there extends the diagonally-extendlng arm 22, the lower end 23 of which extends horizontally. Diagonal bracing strips 24 extend from the rear arm of the beam 20 to the diagonally-extending arm 22 and are positioned upon opposite sides of the standard 17 so that the standard will be prevented from moving transversely. A collar 25 passes around the standard 17 and rear arm 19 of the beam 20, is securely connected to the standard 17 by means of the bolts 26 and 27, and is adjustably connected with the arm 19 by means of a bolt 28 which passes through one of the openings 29 formed in the arm 19. A yoke 30 straddles the bridge 21 and is rigidly secured to the collar 25 by means of the bolt 26 and adjustably connected with the bridge 21 by means of a bolt 31 which passes through the bridge 21 and through a selected set of the openings 32 formed in the. yoke. By this arrangement the standard 17 may be vertically adjusted by removing the bolts 28 and 31 and after sliding the standard 17 along the arm 19 to the desired place, replace the bolts. The standard 17 will then be securely held in the new position. If desired, the yoke 30 may be done away with and the standard held in place by the collar 25 al0ne;'or if preferred, bolt 28 may be removed and standard 17 held in position by yoke 30 and bolt 31.

The forward section 33 of the sub-soiler beam 20 is pivotally mounted upon the bolt 15 within the housing 16 and is provided with a hinge ear 34: through which there passes a bolt 35 which his carried by hinge ears 36 of the extension 37. The extension 37 is secured to the forward portion 23 of the diagonally-extending arm 22 by means of bolts 38, and it will be seen that the rear arm of the beam 20 will be hinged to the front section 33 and thus permitted to have horiacntai jivotal movement. By having the beam of the subsoiler pivotally connected with the beam of the main plow, as clearly shown in Figs. 1 and 2, the subsoiler can be caused to dig into the bottom of the furrow made by the main plow 11 as deep as desired. A bail 13 connected with handles and braces is provided to prevent undue horizontal movement.

It is desired to prevent the subsoiler from rising upon striking hard ground, and therefore the adjustable combination brace shown in Figs. 1 and 4 has been provided. This brace comprises the front and rear bars 39 and 40 which are removably connected together by means of the bolts 41. The front bar is pivotally mounted upon the bolt 42which connects the handle braces 13 with the main plow beam 10 to permit the brace for the subsoiler beam 20 to be moved to bring the bridge 43 0f the head 44 into engagement with the diagonal arm 22 of the beam 20. This head 44 is pro vided with converging arms 45 and 46 which extend from the head 43 and have their end portions 47 and 48 secured to the hookshaped end portion 49 of the bar 40 by means of rivets 50. The head 44 engages the diagonal arm 22 at right angles thereto and is of such width that the subsoiler beam can not move out of engagement with the head. To disengage the subsoiler from the ground, diagonal arm 22 may be placed in hook 49.

In the operation of this device the plow may be used as an ordinary plow by removing the subsoiler and subsoiler brace; or if desired, the rear arm 40 may beremoved from the front arm 39 and the rear section of the subsoiler beam 20 may be removed from the forward section 83. This is done by removing the bolts 41 and hinge bolt 35. When it is desired to use the subsoiler, the subsoiler is connected with the plow as shown in Fig. 1 and the standard 17 is adjusted so that the point 18 will cut into the bottom of the furrow the desired depth. After the standard has been adjusted, the brace is lowered to bring the head 44 into engagement with the diagonal arm 22 of the subsoiler beam. The subsoiler beam will then be prevented from rising in case the point 18 strikes hard dirt. By having the rear section of the subsoiler beam pivotally mounted for horizontal pivotal movement the subsoiler will be permitted to have transverse movement, but it should be noted that the bail 13 for the subsoiler beam will prevent undue horizontal pivotal movement when the subsoiler is in use, and thus prevent the subsoiler from dragging and being wrenched out of shape When taking the main plow from the furrow.

I have thus provided a subsoil plow in which the subsoiler may be easily connected and disconnected. I have provided a subsoiler which is so constructed that the standard may be vertically adjusted and securely held in the adjusted position. I have also provided a subsoiler which will be permitted to freely move pivotally, but which is prevented from vertical movement in one direction by an improved brace pivotally connected with the main plow beam and engaging the subsoiler beam at right angles thereto. It should also be noted that this subsoiler is so constructed that it may be used without danger of breaking or easily getting out of order since the parts are very few and very simple in construction. p
